How Plumbing Licensing Works in Illinois

Illinois requires plumbers to be licensed through the Illinois Department of Public Health (IDPH).

State Rule: You must either complete an approved apprenticeship or pass the Illinois plumber licensing exam after meeting eligibility requirements.

  2. Get an apprentice plumber's license from IDPH.

Tips for Getting Into a Plumbing Apprenticeship

Competition for good programs can be high. Here's how to improve your chances:

  • Apply early-some programs only accept new apprentices once a year.
  • Brush up on math, especially fractions and geometry.
  • Be prepared for an aptitude test.
  • Have a clean driving record and pass drug screening.
  • Show up on time for every step of the process, including interviews.

Warning: OSHA requires proper protective equipment and safety training for all plumbing work involving confined spaces or hazardous materials.

Learn safety rules from the start-they are part of the licensing exam and your day-to-day job.
